WINDOW-CLEANING DEVICE.

retoma. l

To all fwlwmf't may concern: Y l `:,Be it known.l that lf, Josemi R. Ln CLAIR, axcitizenfofthe `.United States, 'residing at lllvandotte.inl the county of Vayne and btate ofV lilichigan, have invented a. new and useful lVindow-Cleaning Device, of whichthe following is a specification. This 'invention relates to window cleaners especially adapted Jfor use on the window of motormans vestibule of street and interni'- ban pars, and it consists in the novel features of construction and operation as hereinafter `set forth and claimed.

`The invention has for its object to provide aisimple and eti'ective cleaning device for lattachmel'it ytothe rameor sash of a window, particularly to the front window of the fmotorfmans vestibule of a street car so aste yieldably and movably bear in engagementwith the-inner and outer the window pane, and which may be Inanually operated to slide in wiping contact across; the planes of the glass in the manner of a squeegee to etl'ect the removal of any accumulation el dust or moistuie thereon and thus enable both sides of the window to be readily cleaned simultaneously.

In the accompanying drawings Ais illustrated a preferred structural embodiment of my invention, and in which,

Figure 1 is a view in elevationo a portion of the from end or motormans vestibille of a street car showing the window y equipped with the present invention in position thereon for operation.

Fig. "2 is a transverse vertical section through the window and upper railoi the Aframe embraced by `the cleaning device, the body portions of which are shown in eleyation engaged with opposite faces of the Window pane.

Fig. 3 is a perspective view of one of the flexible wiping strip, the lower portion of which is broken away.

Eig, i is a horizontal section through the heads oi the supporting brackets mounted' to slide in a slot -formed through the upper rail of the window frame. y

Fig. 5 is a plan view of a leaf spring for applying tension to yieldably retain the bracket heads slidably engaged with the rail of the Window. v

on the drawings, 1 represents the front window of the motormans vestibule of a street car, and indicates the upper cross rail of the window frame having formed transversely therethrough a slot' which extendsl slightly beyond the full width of the window sash 4. A pair of outwardly bowed brackets or supporting arms 5 having rectangular bearing heads (3 at their upper ends are mounted to embrace between the inner faces of said heads the rail Q of the window Yframe from which said arms .depend in opposed alinement upon opposite sides respectively of the window 1, as best shown in Fig. Q. The inner face of each of the heads 6 is provided with a central longitudinal and laterally extending rib 7 which fits 'freely within the slot 3 wherein it slides with the movement ot' said head and serves to steady and retain the arm in the vertical position in traveling therewith longitudinally of said slot. The lower end of each of the arms is formed with an imvardly` turned forked extension 8 within which the folded edge of a sheet metal strip 9'is secured by screws or rivets 10 .to extend in adjacent parallel relation to said arm, and secured between the folded sides of the strip 9 by rivets as at 11 is a flexible strip 12, preferably of rubber, which is adapted to bear upon and wipe the surface of the glass 13 with the movement of said arm transversely across the window. (See Figs. 2 and 3).

ln order to secure the heads in opposed relation slidably engaged with the slot of the to retain the flexible wiping strips yieldably engaged with the opposite faces, respectively, of the window glass, the outer face of each of said heads is provided with a longitudinal recess 14 having a cent 'al transverse opening 1F? therethrough, and seated to bear atopposite ends within these recesses respectively are opposed arcuate leaf springs 16 having central transverse apertures 17 through which and the openings 15 ot'said heads a bolt 1\8 1s extend-ed and provided with a binding nut 19, by means ot which said springs are conned under tension which is exerted upon the heads and bracket arms in a manner to yieldably retain the wiping strips slidably engaged with the wind w glass.
